[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a detachable structure for a smoke collection plate and a range hood having the same structure. Background Technology

[0002] Range hoods have become an indispensable kitchen tool in modern family cooking. In order to prevent or reduce the escape of oil fumes and improve the fume extraction effect, existing range hoods are often equipped with a smoke collection plate. The smoke collection plate has an open and closed state. When in use, the smoke collection plate is opened to facilitate the collection of smoke. When not in use, the smoke collection plate is closed to keep the whole machine clean and reduce space occupation.

[0003] Currently, the smoke collection plates are mainly installed on the smoke collection hood using a hinged method, and are connected to a drive device that switches the smoke collection plates between open and closed states. The drive device occupies a large space, is inconvenient for packaging and transportation, and is costly. In addition, the smoke collection plates are not easy to remove from the smoke collection hood, and cleaning them is time-consuming and laborious. Utility Model Content

[0004] One of the technical problems solved by this utility model is to provide a disassembly and assembly structure for a smoke collection plate, which can effectively solve the problems of difficulty in cleaning due to the inconvenience of disassembling and assembling the smoke collection plate, as well as the large space occupied and high cost of the drive device for driving the smoke collection plate to rotate.

Therefore, they should not be construed as limitations on this application.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] This embodiment proposes a disassembly and assembly structure for a smoke-collecting plate, used to install the smoke-collecting plate 2 on a base, as shown in the reference. Figures 1-6 As shown, the disassembly and assembly structure of the smoke collecting plate includes a snap-fit ​​support 3 and a pin 5. One of the support 3 and the pin 5 is set on the base, and the other is set on the smoke collecting plate 2. There are two of each type of support 3 and pin 5, and they are arranged along the length of the smoke collecting plate 2. Figure 1 (Interval settings in the left and right directions)

[0041] The support 3 has a slot 311. Each slot 311 on the support 3 has a groove facing another support 3 and an opening 3111 on the side wall of the slot. The pin 5 is inserted into the slot 311 and can move within the slot 311 to disengage from the support 3 through the opening 3111. It can be understood that the movement of the pin 5 in the slot 311 is reversible, that is, the pin 5 can also enter the slot 311 through the opening 3111 and engage with the support 3 for limitation, thereby limiting the smoke collector 2 to the base. In other words, the pin 5 can enter and exit the support 3 through the opening 3111.

[0042] The aforementioned disassembly and assembly structure of the smoke collection plate utilizes the snap-fit ​​support 3 and pin 5 to limit the position of the smoke collection plate 2. The smoke collection plate 2 can be disassembled from or installed on the base by simply moving the smoke collection plate 2 manually. This makes disassembly and assembly convenient, reduces cleaning difficulty, and saves packaging and transportation space and reduces costs because no drive device is required.

[0043] refer to Figures 3-6 As shown, the slot 311 is spiral-shaped. When the pin 5 is assembled with the support 3, the pin 5 is limited to the inner circle of the slot 311 and can rotate within the inner circle of the slot 311. Under the action of its own weight, the smoke-gathering plate 2 assembled on the base maintains a drooping posture to cooperate with the base to achieve the smoke-gathering effect. It should be emphasized that, in this embodiment, "the slot 311 is spiral-shaped" means that the slot 311 rotates outward around a central axis.

[0044] Specifically, the slot 311 includes a straight segment 3112 and a curved segment 3113. The inner ring is formed in the curved segment 3113, the straight segment 3112 connects to the end of the curved segment 3113 furthest from the inner ring, and the opening 3111 is located on the sidewall of the slot corresponding to the end of the straight segment 3112 furthest from the curved segment 3113. When the pin 5 enters the slot 3111 through the opening 3111, it first enters the straight segment 3112 and then enters the inner ring along the curved segment 3113. The straight segment 3112 reduces the difficulty of the pin 5 entering the slot 311. It is understandable that the size of the inner ring is slightly larger than the cross-sectional size of the pin 5 to reduce the shaking of the pin 5 within the slot 311 and improve the assembly stability of the smoke collector plate 2.

[0045] In other embodiments, the pin 5 can be set to an ellipse, and the width of the opening 3111 of the slot 311 can be set to be smaller than the major axis of the ellipse but larger than the minor axis of the ellipse. Then, when the pin 5 rotates to a certain angle in the slot 311, it can disengage from the slot 311 through the opening 3111.

[0046] To prevent the pin 5 from accidentally detaching from the support 3, a limiting component 4 is also provided on the support 3. Specifically, the limiting component 4 includes an anti-detachment pin 41 and a reset member 42. The anti-detachment pin 41 is movably inserted into the support 3 to open or block the opening 3111. The anti-detachment pin 41 is provided with a guide surface, and the pin 5 can push the anti-detachment pin 41 to open the opening 3111 through the guide surface. For example, the guide surface is set as a conical surface or a spherical surface. The reset member 42 is configured to keep the anti-detachment pin 41 in a tendency to block the opening 3111.

[0047] Specifically, a mounting hole 322 is provided on the side wall of one groove corresponding to the straight segment 3112. The reset member 42 is located in the mounting hole 322 and is elastically connected to the anti-detachment pin 41 and the support 3. The anti-detachment pin 41 can retract into the mounting hole 322 under the push of the pin 5. To reduce the difficulty of assembling the reset member 42 into the mounting hole 322, an insertion hole 312 is provided on the other side wall of the straight segment 3112, which is aligned with the mounting hole 322. When assembling the reset member 42, first insert the anti-detachment pin 41 connected to it into the insertion hole 312, and then insert the end of the reset member 42 away from the insertion hole 312 into the mounting hole 322. It should be emphasized that when the reset member 42 is in its natural state, the guide surface is at least partially located outside the insertion hole 312.

[0048] In this embodiment, the reset member 42 is a spring, which is sleeved on the anti-detachment pin 41. To facilitate the connection between the spring and the anti-detachment pin 41, a convex ring is also provided on the outer periphery of the anti-detachment pin 41, and the spring is located on the side of the convex ring away from the insertion hole 312. More specifically, the support 3 includes a main body 31 and a mounting part 32, wherein the main body 31 is approximately circular, and a slot is formed on the main body 31. The mounting part 32 is integrally formed with the main body 31 and is located near the opening 3111. A mounting hole 322 is formed on the mounting part 32, and a fixing hole 321 is also formed on the mounting part 32. The fixing hole 321 is perpendicular to the mounting hole 322. The support 3 is fixedly connected to the base or the smoke collection plate 2 by fasteners passing through the fixing hole 321.

[0049] When the pin 5 needs to be inserted into the slot 311, the pin 5 contacts the guide surface of the anti-detachment pin 41. Under the guidance of the guide surface, the anti-detachment pin 41 moves away from the insertion hole 312 and retracts into the mounting hole 322. After passing the anti-detachment pin 41, the pin 5 extends out of the mounting hole 322 under the action of the spring. When the pin 5 needs to be removed from the slot, the pin 5 rotates from the inner ring of the slot 311 to the outside of the slot 311 until it contacts the anti-detachment pin 41. Under the guidance of the guide surface, the anti-detachment pin 41 moves away from the insertion hole 312 and retracts into the mounting hole 322. The pin 5 is removed from the slot through the opening 3111.

[0050] refer to Figures 7-8 As shown in this embodiment, in order to facilitate the installation of the pin 5 on the smoke collection plate 2 or the base, the disassembly and assembly structure of the smoke collection plate 2 also includes a mounting seat 6. Two mounting seats 6 are also provided. The two mounting seats 6 are fixed to the two sides of the length direction of the smoke collection plate 2 or the base by adhesive bonding. The mounting seat 6 is provided with threaded holes for installing the pin 5. The pin 5 is threadedly connected to the mounting seat 6.

[0051] This embodiment also proposes a range hood, which includes, but is not limited to, side-draft range hoods, integrated range hoods, and other range hoods with smoke extraction functions. (See reference...) Figure 1 , Figure 9 and Figure 10As shown, the range hood includes a smoke collection hood 1, a smoke gathering plate 2, a fan 7, and an air box 8. The fan 7 is located inside the air box 8, which is fixed above the smoke collection hood 1 and communicates with the inner cavity of the smoke collection hood 1. The smoke collection hood 1 has an air inlet. The smoke gathering plate 2 is installed on the smoke collection hood 1, which serves as the base, through the aforementioned detachable structure of the smoke gathering plate, to cooperate with the smoke collection hood 1 to form a smoke collection chamber and prevent the oil fumes from escaping. Specifically, in this embodiment, the support 3 is installed on the smoke collection hood 1, and the pin 5 is installed on the smoke gathering plate 2. Preferably, in order to ensure the connection stability between the smoke gathering plate 2 and the smoke collection hood 1, both the support 3 and the pin 5 are along the length direction of the range hood (i.e.,...). Figure 1 There are two interval settings (left and right directions).

[0052] In this embodiment, the smoke hood 1 includes an upper smoke collection section and a lower smoke collection section, which are arranged at an angle and are interconnected. The bellows 8 is fixed to the top of the upper smoke collection section and is connected to it. The smoke gathering plate 2 is located at the end of the upper smoke collection section away from the lower smoke collection section. The smoke hood body is generally shaped like a "7", with the width of the lower smoke collection section being narrower than that of the upper smoke collection section. This design allows the smoke to be close to the kitchen fumes without easily touching kitchen utensils such as pots, thus reducing the space occupied in the kitchen.

[0053] The smoke hood includes a smoke guide plate and side plates located on both sides of the length of the smoke guide plate. The air inlet is opened on the smoke guide plate, and the smoke collection plate 2 is also installed on the smoke guide plate. The side plates extend forward along the front-back direction of the range hood to form a smoke collection wall 14 protruding from the smoke guide plate. The smoke collection wall 14, together with the smoke hood 1 and the smoke collection plate 2, forms a downward-opening smoke collection chamber. The width of the smoke collection wall 14 gradually increases from bottom to top, so as to reduce the occupation of kitchen space while achieving the smoke collection effect.

[0054] Based on the wall adhesion effect, the flue gas rises along the smoke guide plate and then flows towards the smoke collecting plate 2. Under the obstruction of the smoke collecting plate 2, the flue gas will flow back to the smoke collecting hood 1 and then enter the smoke collecting hood 1 through the air inlet, which improves the flue gas absorption effect.

[0055] refer to Figures 10-12As shown, the smoke guide plate includes a first smoke guide plate 11 and a third smoke guide plate 13. The third smoke guide plate 13 is located above the first smoke guide plate 11 and is set at an angle to the first smoke guide plate 11. The first smoke guide plate 11 extends downward, and the third smoke guide plate 13 extends forward. The upper end of the smoke gathering plate 2 is installed on the front side of the third smoke guide plate 13 through a support 3 and a pin 5, and the lower end extends downward. In addition, the front sidewall also includes a second smoke guide plate 12, which is located between the first smoke guide plate 11 and the third smoke guide plate 13 and connects the first smoke guide plate 11 and the third smoke guide plate 13. That is, the first smoke guide plate 11, the second smoke guide plate 12, and the third smoke guide plate 13 are connected sequentially from bottom to top. The second smoke guide plate 12 is a rearwardly concave arc-shaped plate, which can guide the smoke to swirl, making it more convenient to guide the smoke from the first smoke guide plate 11 to the third smoke guide plate 13, and then back to the smoke guide plate after being blocked by the smoke gathering plate 2.

[0056] Specifically, the air inlets include a first air inlet 15 and a second air inlet 16. The first air inlet 15 is located on the first smoke guide plate 11, while the second air inlet 16 is located above the first air inlet 15. To increase the flow velocity of the first air inlet 15 and prevent the flue gas from rising rapidly and bypassing it, the first air inlet 15 is positioned in the middle of the first smoke guide plate 11. Based on the principle that flow rate = area * flow velocity, the first air inlet 15 is designed as a strip-shaped structure extending along the length of the smoke collecting plate 2. Multiple second air inlets 16 are spaced apart along the length of the smoke collecting plate 2, extending vertically. Under negative pressure, the vertically elongated second air inlets 16 can cause the flue gas to move laterally, thus better intercepting the fumes. (Reference) Figure 10 and Figure 12 As shown, when the fumes rise from the bottom and pass through the first air inlet 15, under the negative pressure created by the fan 7, part of them enters the inner cavity of the fume hood 1 through the first air inlet 15, while the rest continues upward through the second air inlet 16. Under the negative pressure, the fumes move laterally and remain at the second air inlet 16 for a longer time, allowing the second air inlet 16 to draw in more fumes into the inner cavity of the fume hood 1. Some of the fumes continue upward and are guided to the smoke collection plate 2. Under the guidance of the smoke collection plate 2, the fumes descend and return to the first smoke guide plate 11, so that they can continue to rise from the bottom and pass through the first air inlet 15 and the second air inlet 16.

[0057] The second air inlet 16 can be located on the second smoke guide plate 12, the third smoke guide plate 13, or the first smoke guide plate 11. (Reference) Figure 12 and Figure 13 As shown, in this embodiment, the second air inlet 16 is opened on the second smoke guide plate 12. The second air inlet 16 opened on the second smoke guide plate 12 is closer to the first air inlet 15 and is located closer to the upper smoke collection part, which can more effectively cause the smoke to move laterally, thereby improving the smoke absorption effect.

[0058] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0059] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
